Natural Herbs to Exterminate and Repel Spiders

Updated April 17, 2017

Spiders may be welcome in the garden where they protect your vegetables from other harmful insects, but there is nothing like seeing a spider walking across a ceiling, floor, or wall in your house to give you the creepy-crawlies. We want to exterminate them quickly but most spider poisons and repellents can be quite toxic. If you have children or pets in your home, consider a natural remedy for killing and repelling spiders.

Essential Oils

Tea tree, citronella, peppermint, lavender, cinnamon, citrus and rose oils will kill spiders and other insects on contact. If you kill all the insects in your home, the spiders won't have food. No food means no more spiders. Mix up to five drops of oil and a teaspoon of dish soap into a one-quart spray bottle. Fill the bottle the rest of the way with water then spray any spiders or insects you find in and around your home. Spiders use small glands on their legs to taste and don't like the taste of these oils, so spray anywhere they might lurk for an effective repellent. Use the solution every couple of months and your spider problems should be a thing of the past.

Chestnuts, Eucalyptus and Hedge Apples

Place chestnuts or hedge apples (also called osage oranges) on window sills and around the exterior walls of your home. The scent of the chestnuts and hedge apples keep the spiders at bay. They also detest the scent of eucalyptus. Place the leaves in corners, drawers, closets, on window sills or under furniture.


Soak a package of chewing tobacco in a gallon of boiling water. When the water has cooled, remove the tobacco. Combine a cup of the tobacco juice with half a cup of lemon-scented dish soap and spray in areas where spiders get into your home or like to hide. Respray the areas again in a month, more often if spider problems persist.

Other Natural Repellents

Keep both the inside and outside of your home free of clutter, providing the spiders less places to hide. Move old vegetation or wood away from the exterior of your house, and clip tree branches and other plants that touch the house. Inspect your home for any cracks where spiders or other bugs may enter and seal any that you find. Check with your local hardware store. They may carry high frequency devices that plug into an outlet and keep bugs and spiders out of your home.
